Factors for Wooden Sleeper Failure
The main reasons for the failure of wooden sleepers are decay, mechanical wear, and cracks. Cracks and mechanical wear can accelerate the decay of wooden sleepers, while decay can exacerbate mechanical wear and the expansion of cracks. Therefore, in measures to extend the service life of wooden sleepers, comprehensive consideration should be given. Let us see them together.
Protection Measures for Wooden Sleepers
- Anti-Corrosion Treatment
Utilize preservatives such as water-soluble sodium silicate to treat wooden sleepers, extending their service life and preventing decay.
- Reduce Mechanical Wear
Increase the area of the pad and decrease the unit pressure on the wooden sleeper's surface to minimize mechanical wear.
- Prevent Cracks
Control the moisture content before anti-corrosion treatment to prevent cracks. For existing cracks, inject anti-corrosion slurry and clamp tightly, then tie with iron wire to prevent further cracking after installation.
- Proper Installation
Lay wooden sleepers of uniform size, strength, and durability together in sections during installation. Choose standard-sized, high-quality materials for joints.
- Orientation and Placement
Place the heartwood downwards and ensure any rounded corners face downwards during installation to enhance stability and durability.
- Gap Prevention
Place anti-corrosion-treated pads or asphalt-coated jute cloth between the pad and the wooden sleeper to prevent the intrusion of dirt, water, or sand, reducing the risk of decay and mechanical damage.
